Why the horses developed an oxygen debt when they exercised.
user100 [1]

Answer:

The horses developed an oxygen debt when they exercise because they suffered from Exercise-Induced Pulmonary Hemorrhage (EIPH).

Explanation:

A temporary shortage of oxygen in the body tissues during physical exertion such as exercise or a sudden burst of activity is referred to as oxygen shortage.

Horses (compared to humans) are uniquely designed to experience little or none of this.

When the body takes up oxygen, it reacts with glucose to produce energy. This is called Aerobic respiration.

There is also another procedure that the body uses to produce energy. This occurs when glucose is broken down in the cells. After this happens, lactic acid is created but cannot be stored in the body and must be expelled.

This interval when energy is produced without the presence of oxygen is called "oxygen debt".

When a horse is fit, its breathing quickly returns to normal. The longer the time taken for the breathing to return to normal, the less fit the horse is.

One of the factors that can reduce the fitness of a horse is the Exercise-Induced Pulmonary Hemorrhage (EIPH).

This occurs when blood vessle in the lung ruptures causing blood to bleed into the airways. So blood occupies space where oxygen should have. This reduced the amount of oxygen delivered to the blood stream. Hence the oxygen debt takes longer to be repaid.

Cheers

.dont taste or sniff chemical

Tasting and smelling some chemicals can be dangerous and even deadly.the best way to know what is in a container is to label

This result in mixing chemcals to see what happens the result could be explosion ,fires,or releasing toxic chemicals

.Dress for the lab

This is a safety rule because clothing is one of your best form of protection against an accident wear covered shoes,long pants,and keep your hair tied so it cant fall into your experiment

1) What happens to the force between two object, if
Zigmanuir [339]

Answer:

<h3>Heyy mate!</h3>

Explanation:

  1. (i) The gravitational force between two objects is directly proportional to the product of masses of the two objects. So, if the mass of one of the objects is doubled, then the force also gets doubled (it becomes 2 times).
  2. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
  3. The distance between the objects is doubled and tripled
  4. Force thus becomes one-fourth of its initial force. Force thus becomes one-ninth of its initial force.
  5. Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. ... If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

Part II: For each of the genotypes below, determine what phenotypes would
Troyanec [42]

Answer:

4. Brown

5. Brown

6. Blue

7. Long

8. Long

9. Short

Explanation:

Dominant alleles are always expressed when they are present. Recessive alleles are masked by dominant alleles.

Therefore, two copies of a recessive allele are required to show the recessive trait. Either one or two copies of a dominant allele produces the dominant trait.

Therefore, for dominant brown eyes, BB or Bb gives brown eyes, bb gives blue eyes.

For recessive long tails, tt gives short tails, TT and Tt gibe long tails
